AARON J. TYLER, OF ALBTO. NE\V YORK.

HYD RANT.

SPECIFICATION forming part of Letters Patent No. 388,798, dated August28, 1888.

Application filed May d, lrPPt-l.

T0 @ZZ whom, it may concern:

Be it known that I, AARON J. TYLER, a citizen of the United States,residing at Albion, in the count-y of Orleans and State of New York,have invented certain new and useful Improvements iu Hydrauts, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

My invention has relation to certain new and useful improvements inhydrants; and it has for its object to provide an extremely simple andinexpensive hydrant that will have but few working parts to get outoforder, and which will at the same time be positive and reliable inoperation, as will fully hereinafter appear.

The invention consists in certain nevel features of construction andarrangements of parts, that will be hereinafter fully described, andparticularly pointed out in the claims appended.

The invention is fully illustrated in the accompanying drawings, inwhich Figure 1 represents a side elevation of my improved hydrant; Fig.2, a vertical longitudinal sectional view ofthe same; Fig. 3, a viewofthe operating or hand wheel inverted; Fig. 4, a side elevation of theconical nut attached to hand-wheel to prevent leakage of water aroundvalve-rod when valve is open; Fig. 5, a plan view of the valve-casingdetached from stand-pipe; Fig. (i, a plan view of same with upper headremoved to show the interior thereof; Fig. 7, a side elevation of valvedetached.

Referring to the drawings by letters, A designates the stand-pipe, tothe upper screwthreaded end of which is screwed the waterchamber thischamber being provided with female threads for this purpose. Thischamber is closed at its upper end and provided with one or more lateraloutlets, (l. The letter D designates the vertical valve-rod, whichextends up centrally through and is journaled in the head a of thewater-chamber B, and on its upper end has attached to it in anycouvenient manner a hand-wheel, l, in the present instance thishand-wheel being held on the valve-rods by means of a jam or lock nut,I), and a conical nut, c. The conical uut c has a central longitudinalscrew-tlneaded passage through it for the purpose of permitting it toSerial No. 272,102

be screwed upon the upper screw-threaded end of the valve-rod, and itsupper cylindrical portion, e', is provided with external screwthreads toenable thehand-wheel to be screwed to it. The lint I upon the extremeupper end of the valve-rod serves to bind the parts securely together.The conical portion of the nut c is fitted closely into a conical recessin the head a of the water-chamber, andthe val verod is held againstvertical movement by means of a collar, (l, secured upon the same andabutting against the lower side of the head a of the water-chamber.

The lower end ofthe stand pipe is provided with external screw threads,whereby the valve casing F may be attached to it, the outlet-opening inthe head lI ot' the val ve-casing being provided with similar femalescrewthreads. This valve-casing is composed of a short cylinder, G,clamped between two flanged heads, ll Il', by means of two or morevertical bolts, e, passing through earsfupou the same, these bolts beingprovided with suitable tightening-nuts. The lower side ofthe upper head,Il, is provided with a circular valvescat, (1, which surrounds theoutlet-opening in this head, and formed vertically through thisvalve-scat and head of the casing is a series of Wasteapertures 71,-.The upper face of the lower head, ll', is also provided with avalveseat, g', which surrounds the inlet-opening f1'. in the head.

\Vorking in the short cylinder G, and adapted to alternately open andclose the inlet 'i andthe waste-apertures l1., is the double-seatedvalve I, which is guided vertically by means of the lugs 7.', formed ondiamctricallyoppov site sides ot' the interior of the said cylinder G.these lugs being embraced by the lugs /.r lr', formed ou the valve, asshown in Fig. This valve is preferably cast in a single piece, andconsists, essentially, of a disk, l, having rising from its edge theslightly-diverging vertical pillars m, which support a ring, n., thisring a having formed on its periphery the abovementioned guiding-lugsIt. The lower disk, l, is adapted to bear, through the medium of apacking-ring, secured thereto, upon the seat g around the inlet-openingand close the same, and the ring a is adapted to bear through the mediumof a packing-ring, n', inserted iu IOO a groove in the same upon theseat g and close the waste-apertures h.

The valve I is adjusted vertically by means of the valve-rod, the lowerend ot the same being screw-threaded and working in a femalescrew-threaded aperture in a boss t'ormed upon the upper face ot' thedisk l. I prefer this method of operating the valve; but it is evidentthat I may use other methods without departing from the spirit of thisinvention.

Secured adj nstabl y by means of a setescrew, or formed integral willithe stand-pipe, is a hood, J, which overhangs the upper head, II, ofthel valve-easing, thereby protecting the Waste-apertures andpreventing` them from becoming clogged. When the doubleseated valve iselevated by means of the valve-rod, the inlet-opening i is opened andthe wasteaperture closed, thus permitting the water to iow freelythrough the hydrant to the outlet C, and when the valve is lowered theinlet opening is closed, so as to shut ott the tlow of water, and thewaste apertures are opened, permitting thc water in the stand-pipe torun off into the surrounding earth, as usual.

It will be observed that when the valve is opened to permit the water totlow through the hydrant the pressure ot" the ring n of the valveagainst its seat will exert a iirm downward pull upon the valve-rod,serving to force the conical nut c closely in its conical seat in thehead a, and thereby prevent the water trom leaking ont through the valverod opening.

lt is evident that I may form the conical nut c integral with thehandwheel without departing from the spirit of the invention.

Having thus fully described my invention. what I claim as new, anddesire to secure by Letters Patent, isM

l. The combination, with a stand-pipe, a water-chamber, B, attached tothe upper end thereof, the head of this water-chamber being providedwith a conical depression in its upper face, a valve-easing attached tothe lower end of stand-pipe and provided with a valveseat, y,waste-apertures being termed through this valveseat, avertically-movable valve in the casing F, adapted to close against theseatr g and close the waste apertures, a valverod for operating thisvalve, this valve-rod being journaled in the head ot the waterrchamberand provided with a conical enlargement, c, adapted to fit the conicaldepression in the head ofthe water-chamber, substantially as described.

2. In a hydrant, the combination of the stand-pipe provided with awater-chamber on its upper end and a valve-casing on its lower end, avertically-working valve in the said casing, a valve-rod for operatingthis valve, this valve rod being `journalcd in the head of' the Waterchamber and provided with acollar, (l, a conical nut, c, screwed to theupperl end ol' the valve-rod and adapted to titcloselya conicaldepression in the head of the water chamber, a handwheel screwed on thisnut c, and a lock-nut, b, screwed on the projecting end of the valverod, substantially as described.

3. The combination, with a stand-pipe, watervehamber, and a \falverod,ol' the valveeasing consisting ot a vertical cylinder, G, se` curedbetween two heads, II II, the upper head, H, being provided withwaste-apertures L, the valve I,working vertically in the cylinderG, andconsisting, essentially, of the upper ring, u, and lower disk, Z,connected by vertical pillars m, the said valve being adapted toalternately close the waste and inlet openings, and the packing-rings,substantially as and for thc purpose herein set forth.

AI. The combination, with the stand pipe, and the valve casing F,secured to the lower end of the standpipe, this valve-casing consistingof a short cylinder and two heads, II II, these heads being provided,respectively, with the valve-seats g g, theformer valve-seat beingprovided with waste-apertures l, and surrounding the outlet in the headII, of the vertically-working valve I', inclosed in the said casing I?and consisting ot the upper ring, n, and a disk, I, connected with thesaid ring by Vertical pillars m, packings secured to the said ring n anddisk l, and a valverod for operating the said valve I, this valve Ibeing adapted to alternately close against the valveseatsy r/,substantially as described.

In testimony whereof I atti v my signature in presence of two witnesses.
